钢筋混凝土构件的界面元分析

INTERFACE STRESS ELECENT METHOD ANALYSIS OF REINFORCED CONCRETE MEMBER

概述了钢筋混凝土结构的有限元模型,针对有限元法模拟钢筋和混凝土两种介质交界面上不协调位移的不足之处,引入界面应力元法,简述了界面应力元法的基本原理,提出了钢筋混凝土结构的界面应力元模型,并通过算例验证界面元法分析的正确性。

A finite element model for analysis of steel-concrete structure is summarized.The incompatible displacement and finite-element method on the interface between the two different materials are difficult to be solved.So interface stress-element method is introduced,in order to solve the problem of incompatible displacement on the interface,a numerical example is given to test validity of interface stress element method.
